TECHNICAL FIELD

The present invention relates to an electronic cigarette, in particular to a replaceable universal atomizing head.

BACKGROUND TECHNOLOGY

The electronic cigarette, now mainly used in some developed countries in Europe and the United States, primarily used to replace traditional cigarettes. With the continuous improvement of living standards in China, people are also constantly pursuing a higher quality of life, and gradually realize the serious harm of smoking; therefore, quitting smoking gradually becomes a common understanding. Therefore, the alternatives such as the electronic cigarette are gradually welcomed by people.

Electronic cigarettes have the same look of cigarettes, and have a similar taste or even better taste than general cigarette tastes. Electronic cigarettes, also like cigarettes, can inhale the smoke, suck out the taste and feeling. Electronic cigarettes are mainly used to give up smoking and to replace cigarettes. Electronic cigarette is a non-burning alternative product, is similar to some of the characteristics of general cigarettes, can be refreshing, and can meet smokers pleasure and the using habit of many years. But it essentially differs from the general cigarettes, because the electronic cigarette does not burn, has no tar, and does not have more than 460 kinds of chemical substances which cause respiratory and cardiovascular diseases produced by burning of smoke, thereby removing the ordinary smoke carcinogens. Electronic cigarettes will not cause passive smoking hazards or environmental pollution.

The atomizer and the battery rod are two major components of the electronic cigarette. The battery rod consists of a PCB board, a rechargeable battery, and various other circuits; the atomizer consists of an atomizing device and a cartridge. The Application No. CN201878765U of a Utility Model Patent discloses an atomizer (see FIG. 10), wherein the atomization device of the atomizer includes a main body 330 of the atomizer, a suction nozzle seat 310, a heating device 311 and a liquid guiding component, wherein one end of the suction nozzle seat provides an atomizing chamber 313, the other end of the suction nozzle seat has a vent hole 314 which communicate with an atomizing chamber, wherein said heat means is fixed in the atomizing chamber; the liquid guiding component includes a suction nozzle and a liquid guiding rope 320, wherein one end of the suction nozzle is inserted into the liquid storage cavity of a liquid storage box, wherein the contacting parts form a liquid seal; the other end of the suction nozzle connects with an atomizing chamber of the suction nozzle seat, wherein said liquid guide rope is wound on the heat means 311; both ends of the liquid guiding rope are introduced into the suction nozzle.

A connecting assembly of the atomizing device 30 is fixed to the other end of the housing 10; the connecting assembly includes a main body 330 of the atomizer, a contacting conductor 331 connected to the heating device 311 by conductors, and a contacting conductor base 332. One end of the main body 330 of the atomizer locating in the housing forms a cavity for receiving and holding the atomizing assembly, the sleeve 312, and the other atomizing assemblies are fixed in said cavity, wherein the sleeve 312 cooperates with the cavity in over surplus manner. The sidewall of the main body of the atomizer is provided with an inlet hole 333 for conducting air which communicates with the cavity. The contacting conductor base 332 is fixed on the other end of the main body of the atomizer exposed the housing 10, wherein two contacting conductor 331 are fixed in the contacting conductor base 332, connecting the power supply positive and negative electrodes respectively, wherein each contacting conductor has a hole for contacting thimble accessing. Further, the outer surface of the main body 330 of the atomizer has a step, the main body 330 of the atomizer for supporting the atomizer assembly firstly, and for connecting the power supply apparatus secondly.

The atomizing apparatus of the above-described structures can atomize the liquid smoke, but also has the following disadvantages:

Firstly, the configuration of the atomizing device is a heating device, heated by a battery-powered and making the surrounding electronic cigarette juice volatilized to form the smog, which makes the suction time to reach the effects of the “puff”. Traditional electronic cigarette atomizer with the housing is a unibody, and the atomization device can be used just a few days and cannot be replaced after damage, and the use cost is high. If you have been using a separate atomizing device for a long time, the taste is very poor, and the amount of smoke is also very small;

Secondly, the two contacting conductors 331 are a conductive positive electrode and a negative electrode, respectively; the electrically positive and negative electrodes and the both ends of the heat means 311 are welded by the wire; Because the outer diameter of the main body 330 of the atomizer is only 10 mm and the assembly of these parts is by hand, it is a high difficulty and increases the labor intensity;

Thirdly, since the concentration of the liquid smoke itself is relatively high, while in the suction nozzle is provided a liquid guiding rope, which occupies the space of the suction nozzle, resulting in the liquid smoke flowing downward slowly. On the other hand, when the liquid smoke is flowing, the heat means 311 has been working, due to the flow seed of the liquid smoke is slower than the operating speed of the heating apparatus, i.e., only a small portion of the liquid smoke can reach the heating device, it does not meet the normal proportion of required liquid smoke, the gas in the mouth is a dry taste, this phenomenon is called dry combustion.

Referring to FIGS. 1 to 3, a universal atomizing head 10 of the present invention, which comprises a support base 100 with an atomizing chamber, a heating device 101, a conductive ring 102, and a liquid guiding member. The support base 100 is made of ceramic, in order to install the heating device 101, an atomizing chamber 103 is provided in the support base 100. In order to permit the gas to enter into the atomization chamber 103, a vent hole 104 is provided in the bottom of the support base 100. The heating device 101 is a heating wire made of the metal, fixed to the atomizing chamber 103 of the support base 100; both ends of the heating device before assembled into a universal atomizing head are welded with the wire. On one hand, the conductive ring 102 is a conductive negative of the universal atomizing head; on the other hand is used to mount other components.

Referring to FIG. 1, said support base 100 is fixed in the middle of the conductive ring 102 cavity, pressing a wire connected to one end of the heating device between the conductive ring and the support base, making the conductor and the conductive ring maintain good contact, so that, while using this way, without welding the conductive anode and the heating device artificially, which can reduce process and labor intensity. Referring to FIG. 3, in order to be able to reduce adverse effects on the universal atomizing head produced by a little atomized liquid smoke refluxed to the universal atomizing head, a layer of a liquid absorbing member 105 is wrapped in the outer surface of the support base 100, which is a nickel mesh.
